Abstract
This study deals with the indoor air quality (IAQ) measured and perceived in a demonstration building via a smart sensor. The analysis subject targeted includes the following main air pollutants, viz., CO2, VOCs, formaldehyde, benzene, CO, PM2.5, and comfort parameters such as air temperature, and relative humidity. These were recorded during three campaigns. It turned out that the CO2 level was higher during the first occupation period, while measurements of other air pollutants were low. Besides, it turned out that the ventilation system could regulate control the airflow based on the CO2 concentrations only. However, this was upset occupants comfort.
